Field theory actions for ambitwistor string and superstring
Nathan Berkovits, Matheus Lize
We analyze the free ambitwistor string field theory action for the bosonic string, heterotic string and both GSO sectors of the Type II string. The spectrum contains non-unitary st…

Equations of motion from Cederwall's pure spinor superspace actions
Nathan Berkovits, Max Guillen
Using non-minimal pure spinor superspace, Cederwall has constructed BRST-invariant actions for super-Born-Infeld and supergravity which are quartic in the superfields…
